I've recently ran into a problem with a tranny swap. I pulled out the original 3 speed column tranny and tried putting a 4 speed toploader from a 50 3/4 ton in but the splines are a different size on the shaft in the torque tube from the 1/2 ton than those on the coupler on the tranny. Is there a conversion for adapting the two together or am I beating a dead horse. If so what would be my best option for puting a floor shifter in my 49 1/2 Ton.
Thanks
Jason
